Carrier Thermostat Question

Could somebody please explain the functional difference between the "EdgeProgrammable Thermostat (says it has humidity control) and the older "Performance Thermidistat"? Other equipment includes one speed Performance outdoor unit ( very quiet) and the FV air handler.

The "Edge" definitely looks nicer and is very quiet. However, I am interested in the functional differences and the effect of those differences .... if there are any.

Carrier/bryant Dehum Option

Remember for dehumidification with variable speed fan motor, you need to run an extra wire to the DeHum terminal on the fan blower control board. Then the J1 jumper needs to be removed off the board as well.

WARNING:IF YOU DON'T KNOW THEN DON'T DO, SO THOSE WHO KNOW WHAT YOU DIDN'T KNOW DON'T END UP UNDOING WHAT YOU DID SO IT COULD GET DONE RIGHT!
